How South Africa's wealth is built
South Africa's biggest fortunes span mining, luxury goods, financial services, retail, technology and pharmaceuticals. Names like Johann Rupert (Richemont), the Oppenheimer family (De Beers), Patrice Motsepe (African Rainbow Minerals) and Koos Bekker (Naspers) sit at the top, but the list reaches across the economy — from banking founders to healthcare entrepreneurs.
The Rateweb South African Billionaires Index estimates each person's net worth from publicly available information: listed-company shareholdings valued at current share prices, disclosed transactions, and credible reporting on private holdings. Where a figure is harder to verify, we lower its confidence rating rather than overstate it.
